Most of us are aware that taking breaks from physical activity is necessary to recover and prevent injuries. Taking breaks in our mental work is equally helpful.
Recent studies show that those who give in to some kind of distraction once an hour perform better than those who just keep at it without a break. After a while,our brains can't focus so well,and we become unable to continuously treat the task as important. Taking a break allows us to come back to the job at hand with renewed energy and a sense of purpose.
No matter how much we love our work,we cannot keep creating when we are on empty. Something as simple as a ten-minute conversation with a friend,or watching an inspiring video can give us much needed help,or point us in a new direction if we* re stuck. It is difficult to see things from a new point of view when we come at it the same way all the time. Taking a step away might be just what we need to (恢复精力) .
We are not designed to sit around all day. As difficult as being sedentary(需要久坐的) is on our bodies,it's not helpful for our creativity and productivity,either. Getting up for a few minutes and getting our blood flowing and some more oxygen to the brain are a necessary piece of the v^ork day.
If you know you typically have an afternoon energy slump(锐减)， consider doing exercise during the lunch-time hours. Studies have shown that appropriate activity can boost creativity and productivity for two hours afterward. Plus,the change of scene and focus may just be something you need for your next breakthrough at work.
The next time you feel guilty about taking a break, consider how much more effective it may make you in the long run.
